De conferentie droeg de titel “Private law and market regulation – interaction, interference or inconsistency?”. Het centrale…

Bij Studeren à la carte of toehoorderschap is er sprake van aanschuifonderwijs: u schuift aan bij een reguliere collegereeks, zonder dat u tentamen aflegt. Na afloop ontvangt u een certificaat van deelname. Hierop staan geen studieresultaten (er is immers geen tentamen afgelegd).

Op 12 september 2019 verdedigde Michiel Rhoen zijn proefschrift 'Big Data, Big Risks, Big Power Shifts: Evaluating the General Data Protection Regulation as an instrument of risk control and power redistribution in the context of big data'. Het promotieonderzoek is begeleid door promotoren prof.dr.mr.…

The role of the interfacial environment during electrochemical reactions has been increasingly valued, especially for those reactions involving protons or hydroxyl ions.

Understanding interactions in quantum many-body systems remains one of the most profound and difficult challenges in condensed matter physics.

BlaC is the β-lactamase of Mycobacterium tuberculosis. We show that it can recover from inhibition by clavulanic acid and that phosphate helps it do so.

Docenten spelen een cruciale rol bij het implementeren van onderwijsvernieuwingen. Uiteindelijk hangt het succes van de implementatie af van de manier waarop docenten de vernieuwing vormgeven in hun dagelijkse lespraktijk.

Quantum computers are a proposed fundamentally new type of computer. They aim to perform some computations much faster than previously possible by exploiting phenomena at the quantum scale, called superposition and entanglement.

Indigenous Latin American artifacts have attracted the interest of Europeans since the earliest moment of contact between Europeans and the Indigenous peoples of the Americas. The ERC-funded BECACO project uses an innovative multidisciplinary framework to investigate the provenance of ethnographic and…

In this thesis, we used genetically engineered mouse models to identify genes and pathways that are involved in ILC formation and in the development of resistance to FGFR-targeted therapy.

Carbon dioxide capture and utilization technologies are necessary to create a truly circular economy. The electrochemical reduction of carbon dioxide to formate is an appealing carbon utilization method as it can be performed at room temperature and pressure, it only requires two electrons, and it has…

There is accumulating evidence for an increase in severe global drought events. In particular, Europe experienced several severe droughts in 2003, 2015, and 2018 (unprecedented in the past 2,110 years). Such droughts have caused serious and far-reaching impacts on terrestrial ecosystems.

Catalysis is of extreme relevance in the production of everyday materials and plays a central role in many aspects of our life.

Over the last decades, aviation safety has improved strongly. As a downside, airline pilots do not have as many opportunities to develop through experience the competencies that they need in critical situations.

The subject of this thesis, ‘Approach to Markov Operators on Spaces of Measures by Means of Equicontinuity’, combines an analytical and probabilistic approach to Markov operators.

Nanoparticles can be used as delivery systems for both small molecules and macromolecules such as proteins, peptides or oligonucleotides. This thesis focuses on the use of liposomes, nanometric vesicles formed by a lipid bilayer enclosing an aqueous core. Liposomes are highly versatile delivery syst…

To improve cancer treatments, personalized medicine approaches have aimed to identify exactly which mutations are driving tumor development in a given patient and specifically target these mutations using precision therapies.

In the first part, we introduce a new condition, called toric-additivity, on a family of abelian varieties degenerating to a semi-abelian scheme over a normal crossing divisor.

Cytotoxic T-cells (CTLs) are involved in the clearance of viruses and killing of tumor cells.

The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).

Promotor: B. van de Water

In this thesis, we present new laboratory data of interstellar dust analogues.

One of the key discoveries in exoplanet research over the past decade is the abundance of small planets in our Milky Way. Despite their high numbers, our understanding of their atmospheres remains limited, and it is unknown if they possess atmospheres at all.

Acute cardiovascular syndromes, including myocardial infarction or stroke, are the principal cause of death in the Western society. The main underlying pathology of cardiovascular diseases is atherosclerosis, which is caused by the accumulation of lipids and inflammatory cells in the vessel wall, in…

Sorghum (Sorghum bicolor) is a major cereal crop that millions of subsistence farmers in Sub-Saharan Africa (SSA) rely on. However, the scourging impact of the root parasitic weed Striga (Striga hermonthica, a.k.a. “witch-weed”) has remained a major constraint hampering the productivity of sorghum in…

The outbreaks of AIDS and COVID-19 showed clearly how infectious viruses can influence people’s lives. Investigating the changes in the host metabolism may provide a paradigm shift to consider immune-metabolic interactions as therapeutic targets.

Het Leids Astronomisch Dispuut Frederik Kaiser is een vereniging die zich inzet voor de studenten die in Leiden sterrenkunde studeren.

Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…
